Lieutenant General Roger Handasyd, also spelt Handaside, (11 March 1689 – 4 January 1763) was an English military officer and Member of Parliament for different seats between 1722 and 1754. Often cited as one of the longest serving officers in British military history, in reality he saw little active service. First commissioned in 1694 at the age of five, he was too young for the 1689-1697 Nine Years War and spent most of the 1701 to 1713 War of the Spanish Succession on garrison duties in Jamaica. Appointed colonel of the 22nd Foot in 1712, he transferred to the 16th Foot in 1730, a post he retained until his death in 1763.
